【摘要】：目的探讨音乐测试材料在可接受噪声级(acceptable noise level,ANL)测试中应用的可行性。方法选取国家普通话水平测试用短文朗读作品、普通话音乐、伴奏音乐三种音频材料,制作成ANL测试材料,背景噪声采用目前国际上通用的多人谈话的语频噪声(babble噪声),对40例听力正常青年进行ANL测试并分析结果。结果普通话短文测试材料、普通话音乐测试材料和伴奏音乐测试材料下得到的最舒适响度级(most comfortable loudness,MCL)分别为39.10±7.43、43.85±9.53、44.10±10.83dB HL;最大背景噪声级(background noise level,BNL)分别为37.91±8.65、44.52±11.23、43.65±12.89dB HL;ANL值(MCL-BNL)分别为0.98±4.90、-0.90±3.78、0.45±4.65dB。普通话音乐测试材料和伴奏音乐测试材料下的MCL值和BNL值均高于普通话短文测试材料(P0.05),但普通话音乐测试材料与伴奏音乐测试材料下的MCL值、BNL值均无统计学差异(P0.05),三种测试材料之间的ANL值均无统计学差异(P0.05)。结论音乐测试材料可应用于可接受噪声级测试;在音乐测试材料下MCL值和BNL值更高,提示正常人对音乐的接受度更高,音乐测试材料有无歌词对ANL测试结果没有影响。

Methods three kinds of audio materials, namely, short text reading works, Putonghua music and accompaniment music, were selected for the national Putonghua proficiency test to make ANL test materials. the background noise was based on the babble noise, which is commonly used in the world at present. 40 young people with normal hearing were tested by ANL and the results were analyzed. Results the most comfortable loudness levels of Putonghua short text test materials, Putonghua music test materials and accompaniment music test materials were 39.10 卤7.43, 43.85 卤9.53 and 44.10 卤10.83dB HL;, respectively. The maximum background noise level (background noise level,BNL) was 37.91 卤8.65, 44.52 卤11.23, 43.65 卤12.89dB HL; ANL (MCL-BNL) was 0.98 卤4.90, 鈮，
